This tutorial delves into the technical intricacies of the Lonely Binary ESP-01S PIR Sensor kit. It's a powerful tool for monitoring any room with precision and receiving instant notifications on your iPhone in response to intrusions or movements within your home. Prepare for a comprehensive technical guide to enhance your security system.

To make this setup possible, we employ IFTTT as an intermediary. The Lonely Binary ESP-01S PIR Sensor kit communicates with the IFTTT Webhook Server using the HTTP Post method. Subsequently, the IFTTT Server triggers a Telegram bot, which, in turn, sends notifications to your Telegram client on your mobile device or desktop. This arrangement ensures that you can receive notifications from any location, provided there's an internet connection.

IFTTT, an acronym for "If This Then That," operates as a web-based service and mobile app that allows for the creation of applets. These applets establish connections between various online services, applications, and devices. They function on a conditional logic framework, responding to specific events with predefined actions.

But the technical marvel doesn't stop there. The code also reveals the implementation of Arduino OTA (Over-The-Air) updates. OTA functionality allows for remote software and firmware updates via wireless network connections. This means you can perform code modifications and updates without the need for a physical connection to the ESP-01S. It's a significant convenience for streamlined development and maintenance.

The Lonely Binary ESP-01S PIR Sensor kit, equipped with the power of IFTTT and OTA updates, is your gateway to advanced security and automation. Dive into the technical realm and unlock the full potential of your monitoring system

Here are five steps:

1. Assemble the Lonely Binary ESP-01S.
2. Create applets on the IFTTT website and obtain the WebSocket Key to be used in the code, and link IFTTT with your telegram account
3. Modify and upload the code to your ESP-01S using the Lonely Binary ESP-01S Type-C Programmer.
4. Install the Lonely Binary ESP-01S PIR on any room.
5. Enjoy notifications from anywhere in the world.
